NUF6401MN is a six-channel (C-R-C) Pi-style EMI filter array with integrated ESD protection. Its typical component values of R = 100Ω and C = 17 pF deliver a cutoff frequency of 110 MHz and stop band attenuation greater than -30 dB from 800 MHz to 3.0 GHz. This performance makes the part ideal for parallel interfaces with data rates up to 74 Mbps in applications where wireless interference must be minimized. The specified attenuation range is very effective in minimizing interference from 2G/3G, GPS, Bluetooth® and WLAN signals. The NUF6401MN is available in the low-profile 12-lead 1.35 mm x 3.0 mm DFN12 surface mount package.
The NUF6401MN is a six‑channel (C‑R‑C) Pi‑style EMI filter array that incorporates 8 kV IEC61000‑4‑2 Level 4 ESD protection on each channel. It uses 100 Ω series resistors and 17 pF capacitors to achieve a 110 MHz 3 dB cutoff and more than ‑30 dB stop‑band attenuation from 800 MHz to 3 GHz, all in a low‑profile 12‑lead DFN12 package (1.35 mm × 3.0 mm).
Typical applications include EMI filtering for LCD and camera data lines, I/O ports, and keypads. Ordering information, pin descriptions, electrical characteristics, and performance curves are provided, along with package dimensions and soldering guidelines for designers.
